I work with a team of experienced 3d modellers which should be able to help you at very affordable rates.

In order to give you an estimate it would be useful to get some pictures of the locomotives you have in mind and an indication of the material you want to use and size of the models so we can assess the level of detail we can go into.

Feel free to send the details to uvegter@yahoo.co.uk and I wil come back to you as soon as possible.
